MTN on EMERGRNCY CALLS ONLY IN MY AREAS!!!WE CANT WORK!

MTN is NOT working at all in my area. Since the 28th of May 2021. I work from home and my router and work phones are MTN and now I need to go and park at the garages in town to get a signal. It is just "EMERGENCY CALLS ONLY" there is nothing we can do. Please assist as we are struggling. I live in PMB ELANDSKOP!!!
